Abstract
The invention relates to a breeding method of a Jinling Ma black-bone chicken complete set line, which comprises the following steps: locked breeding, pure breeding and family breeding are respectively carried out on the lake Nanjing China black-bone chicken, the Guangxi black-bone chicken and the recessive white feather breeding chicken, and the ancestral lake Nanjing China black-bone chicken, the ancestral Guangxi black-bone chicken and the ancestral recessive white feather breeding chicken with stable genetic character and variation coefficient less than 10 percent are obtained; breeding parent breeding hens: the method comprises the following steps of taking a grandfather Guangxi black-bone chicken as a male parent and a grander recessive white feather breeding hen as a female parent to perform hybridization to obtain a next generation of hen as a female parent of a parental breeding hen, and selecting a grander lake south Jing black-bone chicken which grows robustly as a male parent of the parental breeding hen; feeding and managing parental breeding hens: carrying out special feeding and management according to production needs; and (3) breeding of Jinling Ma black-bone chicken: the next generation is Jinling Ma black-bone chicken through the hybridization of father and mother breeding hens. The Jinling Ma black-bone chicken bred by the method has the advantages of rapid growth, strong disease resistance, high packaging value, theft prevention and the like.
Description
Technical Field
The invention relates to the technical field of poultry breeding, in particular to a breeding method of a Jinling Ma black-bone chicken complete set line.
Background
The black-bone chicken is also called black-bone chicken and is divided into white-hair black bone, black-hair black bone, mottled black bone, full-black bone and white-bone black meat. The black-bone chicken has the characteristics of light body type, rich nutrition and early maturity. The hydrolyzed whole black-bone chicken powder contains 18 amino acids including 8 amino acids essential to human body, 10 of which are higher than that of common broiler chicken, and carotene and vitamin c are higher than those of common broiler chicken, so that the black-bone chicken powder can be used as medicines, has the effects of building body, beautifying, tonifying qi and nourishing blood, has unique effects on deficiency of qi and blood, mental fatigue, irregular menstruation, abdominal pain, weakness of spleen and stomach and the like, and also contains various trace elements and major elements such as calcium, phosphorus, iron, chlorine, sodium, potassium, magnesium, zinc, copper and the like, thereby being deeply loved by consumers. However, the traditional black-bone chicken has the defects of slow growth, weak disease resistance, low laying rate of breeding hens, low reproductive performance and high variation coefficient, so that the breeding benefit of the black-bone chicken is low, and the requirement of large-scale breeding of the black-bone chicken is difficult to adapt.
Disclosure of Invention
The invention aims to solve the technical problem of breeding parent generation chickens and commercial generation chickens of the Jinling Ma black-bone chickens by three-line matching.
In order to solve the technical problems, the invention is realized by the following technical scheme: a breeding method of a Jinling Ma-Wu chicken complete line comprises the following steps:
1) breeding the ancestral breeding hens: performing locked breeding on lake south Jing state black-bone chicken, Guangxi black-bone chicken and recessive white feather breeding hens respectively, gradually eliminating variant individuals to obtain a population with basically stable appearance characteristics, performing pure breeding on the lake south Jing state black-bone chicken, Guangxi black-bone chicken and recessive white feather breeding hens obtained through locked breeding, performing breeding according to the appearance characteristics and the production performance, selecting pure and bred excellent individuals to establish a 0 generation family core group, performing family breeding for more than 8 generations, and obtaining ancestral lake south Jing state black-bone chicken, ancestral Guangxi black-bone chicken and ancestral recessive white feather breeding hens which have stable genetic characters and less than 10% of variation coefficient;
